I'm installing my timing chain on my 22re and i was wondering if it was alright if my chain is touching the guide

it's been awhile since I've done one but if i remember correctly the drivers side does touch the guides but once it's under load it shouldn't ride them so much.

Mostly you want worry about the drivers side having all the tension and the passenger side having the slack. As long as your sprox-dimples and bright links are lined up everything else should be alright ;o]

>>>*On the passenger side of course the chain does ride on the curved guide, on the driver's side there should be a tiny amount of clearence at all points.

In other words, the straight guide can even barely brush but should not deflect the chain.

*When using the OEM style nylon guide, it is fairly forgiving and just moves out of the way, using any aftermarket steel gaurd it is important to get the rail aligned squarely. Since the holdown bolt holes are drilled off a casting pad template they can vary slightly as to location from one engine block to another.

*Sometimes mild adjustment of the holes in the guide itself are helpful in getting it just right....*EB

It's normal to have a bit of contact. The guides are there for a reason!

thanks for the help. another question, i changed my timing less than 10k miles ago and it recently broke. would a guide becoming loose cause it to break? and what my chances of my valves being messed up?

Have you ever loosened all the rocker arms, removed the timing sprocket, and tried turning the cam by hand? When I first got my truck, the cam was practically siezed from someone overtorquing the cam bearing saddles. You should be able to spin it easily by hand if the springs are not being compressed.

When you replaced the timing chain, did you make sure the master links lined up with the dots on the cam and crank sprockets?

A timing chain should last more than 10k miles even if the guides are loose. The chain will usually rub inside of the timing cover for a while before you have an actual failure. It makes a hell of a warning noise - ask me how I know <img src="/forums/images/graemlins/lol.gif" alt="" />

Do a leakdown test, or if someone has a boresight tool you can borrow, pull the plugs and inspect the piston tops.
